Question

19. Point O is the centre of the circle; DB is a diameter, <OAD = 60
Determine the values of w, x, y, and z.
Justify your solutions.
I got w as 30 and x as 60 pls find x and y
​

Answer 1

Step-by-step explanation:

Firstly I would find the angle X

$od = oa(radius \: of \: circle)$

therefore ∆ OAD is isoceles

therefore /_OAD=/_ODA

/_ODA=60

60+60+X=180(ANGLE SUM PROPERTY OF TRIANGLE)

X=60

y=90-60(angle subtended in a semi circle)

y=30

z=60-30

z=30
